Product Details

The Blue Sea Systems 5129 is a 200-amp ANL (Automotive/Marine Nickel Link) fuse designed for heavy-duty DC circuit protection in marine and automotive applications. This high-capacity fuse provides reliable overcurrent protection for large battery banks and high-amperage electrical systems.

Key Features:

  • 200 amp rating for high-current circuit protection
  • Ignition protected conforming to SAE J1171 standards—safe for installation aboard gasoline-powered boats
  • Silver-plated connector blades provide excellent corrosion resistance in marine environments
  • Visual indication of blown condition for easy troubleshooting
  • 6,000 Ampere Interrupt Capacity (AIC) satisfies ABYC requirements for main DC circuit protection on large battery banks
  • Designed for use with Blue Sea Systems ANL fuse blocks

ANL fuses are the industry standard for protecting high-amperage DC circuits in marine, RV, and automotive applications. The silver-plated terminals ensure reliable electrical contact and resist the corrosive effects of moisture and salt spray. The clear visual indication makes it easy to identify a blown fuse during system diagnostics.
